How to convert HTML to a base64 image with Playwright and Python

The most popular way to do it is with the Grover gem. Grover is a wrapper around Playwright that makes it easy to generate images from HTML.

Install Playwright and Playwright client for Python

pip install pytest-playwright
playwright install

Get the base64 encoded image of some HTML

import asyncio
import base64

from playwright.async_api import async_playwright

async def main():
    async with async_playwright() as p:
        browser = await p.chromium.launch()
        page = await browser.new_page()
        await page.set_content('<html><body><h1>Hello World</h1></body></html>')
        image = await page.screenshot()
        print(base64.b64encode(image))
        await browser.close()

asyncio.run(main())
